Abstract

The polarization of Ξ0 and Ξ̄0 hyperons produced by 800GeV/c protons on a BeO target at a fixed targeting angle of 4.8 mrad is measured by the KTeV experiment at Fermilab. Our result of 9.7% for Ξ0 polarization shows no significant energy dependence when compared to a result obtained at 400GeV/c production energy and at twice our targeting angle. The polarization of the Ξ̄0 is measured for the first time and found to be consistent with zero. We also examine the dependence of polarization on production pt. © 2007 The American Physical Society.
